The invention has for its object to provide an improved jar of this kind by means of which the jar will be eflectively sealed and the jar rendered air tight.

Another object of the invention is to provide an improved jar of this kind in which a disk and ring may be simultaneously employed in connection with thecover, or either the disk or the ring employed.

These and other objects of the invention will appear in the course of thefollowing specification.

Referring to the accompanying drawing, Figure l is a View in elevation of the lower portion of a jar nested on the cover of a jar constructed in accordance with this invention, and. showing the upper portion of the jar. Fig. 2 is a view in vertlcal' section of the 11 per portion of a jar constructed in accordance with this invention.

In carrying out the invention, 1 is the body of the jar having its neck formed with the annular flange 2, beneath which is located the annular groove 3 in which is located a portion of. the clamping wire 4. The upper side of the flange 2 serves as a seat for the rubber ring or gasket 5 which is of the usual flat form. In order to provide a tight joint and have the ring 5 hug the neck of the jar closely, the neck is formed with the annular groove 6 at one-side of the ring seat, as shown in Fig.' 2, the ring 5 being pressed into the groove 6. To further provide for a tight joint between the ar and its cover, the upper edge of the neck of the jar is formed with the bevel 7 which terminatesin a sharp biting edge 8. The cover 9 of the jar is formed with theannular curved rib 10 which provides a recess in which the lower end of a jar 11 may be seated or nested.

Application filed March 9, 1910. Serial No.

tween the side of The cover 10 has a depending annular flange 12 having its lower end formed with a bevele d surface 13 terminating in a shar biting edge 14, which, when the cover 9 1s forced down onto'the neck of the jar, will bite into the ring or gasket 5 and force it not only into the roove 6, but also up beshown in Flg. 2.

In addition to the ring 5, a disk 15 is employed preferably of paper coated with paraflin, the disk 15 being seated against the ange 12 and the neck of the ar, thereby forming a tight joint, as

under side of the cover 9, and extending a over the upper edge of the neck of the jar to the inner side 'of' the flange 12 of the cover. When the cover 9 is ressed down on the neck of the jar b the o amping wire 4,

the bitin edge 8 of t e neck of the jar will.

be force into the disk 15 and form a tight joint therewith, as shown in Fig.2.

It will be seen that by means of the construction hereinbefore set forth, the space between the cover and the neck of the jar will be doubly sealed by the ring and disk. In order that either a rin or d1sk may be used alternately alone wlth the jar and a cover, the jar and cover are so constructed that without the disk and ring, the biting edge 14 of the cover will rest on the top of the annular flange 2, and the biting edge 8 of the neck of the jar will bear against t e under side of the cover, and when a ring or disk is employed alone, the bitin edge which does not impinge against a" isk or ring will not rest against the cover or flange as the case may be.

Itwill be seen that by means of this invention the jar and cover will be completely sealed.

What I claim as my invention is In a device of the character described, a jar having its neck formed with a vertical annular portion havlin formed with a beveled iting e e and a horizontal annular flange .locate at the lower end of said vertical annular portion with a groove in the lowenpart of said vertical annular portion adjacent to the top of said annular flan e in combination with a cover having a e ending annular flange having its lower en formed with a beveled biting edge adapted to be located adjacent to the said annular flange and adjacent to its upper edge Q I I 978,684
